I realize this is hard to answer, but I'll give you the brief story. 3 years ago, our son was conceived via our first ivf. We had 4 frozen embryos left.

Starting this March, we did a FET. It was a chemical pregnancy. After that we did another FET in May, then an ICSI in July (dh's sperm ended up being abnormal) and another FET in Sept. We had an additional 3 frozen embryos that didn't make the thaw and thus we had only 1 go at frozen.

Our embryos always appear good and my lining is fine. I've been on metformin for pcos, progesterone injections, estrase (high dosage if fet, low dosage if ivf/icsi) , baby aspirin...and for our last fet, fragmin and prednisone as well (only 5mg/day).

What could be going wrong this time around as everythign appears to be perfect? It's so strange too as our first ivf worked with no issues (we even implanted 3 embryos and all 3 initially took). I'm at a loss and am losing hope.
